        <pre>with VS 2019 SVML intrinsic "svmlintrin.h" are included by immintrin.h.

As such clang-cl needs to support SVML intrinsics to be compatible with VS2019.

Small Code example: 

#include <immintrin.h>
#include <array>
#include <iostream>

int main()
{
    using Vector = std::array<double, 4>;
    Vector MyData;
    Vector SinData;
    Vector CosData;

    MyData = { 0.0, 1.31, -3.21, 0.51};
    *(__m256d*)(SinData.data()) = _mm256_sincos_pd((__m256d*)CosData.data(),
*(__m256d*)(MyData.data()));

    for (auto elem : SinData)
    {
        std::cout << elem << '\t';
    }
    std::cout << '\n';
    for (auto elem : CosData)
    {
        std::cout << elem << '\t';
    }
    std::system("pause");
    return 0;
}</pre>
